The remaining states with income taxes only selectively conform to the federal tax code. • Twenty-four states tax or potentially tax Global Intangible Low-Taxed Income (GILTI), of which 17 have issued guidance; in most cases, this represents the states’ first significant foray into the taxation of international income. • State tax systems were not made to accommodate international income, and many of the resulting tax regimes give rise to serious constitutional questions. • Twenty-four states provide a deduction for Foreign-Derived Intangible Income (FDII), though seven states which currently tax GILTI do not. • When the federal tax code transitioned from a worldwide to a quasi-territorial system, deferred foreign earnings were “deemed” repatriated and taxed at a preferential rate, a provision captured in the tax codes of 14 states—often without the preferential rate. • Sixteen states conform to an important pro-growth element of federal tax reform, the provision providing for immediate expensing of investments in machinery and equipment. Another three states conform with partial addbacks. • States have delayed long enough. In 2020, policymakers should clear up any remaining uncertainty and use the TCJA, however belatedly, to better orient their states toward growth. FISCAL FACT No. 682 Dec. 2019 Jared Walczak Director of State Tax Policy Erica York Economist TAX FOUNDATION | 2 Introduction Two years is an eternity in politics but a fleeting moment in state taxation, where systems can be slow to respond to exogenous shocks—particularly one like the Tax Cuts and Jobs Act (TCJA) of 2017, and especially when there are competing visions and goals in play. It is, therefore, unsurprising that even two years out, states are still grappling with whether and how to align their own tax codes with the new federal law. Nor is it surprising that the areas of greatest uncertainty would be ones like the treatment of international income. But the normal churning of revenue decisions is a poor excuse for the glacial pace at which some states have offered guidance on how companies should calculate and remit tax on their Global Intangible Low-Taxed Income (GILTI), especially when the expectation is that liability is already accruing. States should, ideally, exclude GILTI from their tax codes—and should make it clear when they do so. Selective approaches to conformity which sever logically related provisions, moreover, continue to populate state tax codes. Conformity with the Internal Revenue Code (IRC) has, historically, been a rote annual process in most states, if not one set on autopilot through “rolling conformity.” The Tax Cuts and Jobs Act temporarily upended this sleepy realm, breathing new life and outsized significance into a normally routine chore. In many states, conformity is falling back into its old routine, but in others, TCJA conformity remains front and center even though, in nearly all cases, the conformity dates now reflect a post-TCJA world, because those states have introduced complexities, uncertainties, and non-neutralities that have yet to be resolved. This paper, which updates several key components of our January 2019 tax conformity paper,1 examines how states have approached provisions closely tied to the competitiveness and neutrality of the tax code, including taxation of GILTI, provision of the deduction for Foreign-Derived Intangible Income (FDII), inclusion of income deemed repatriated under § 965, the first-year expensing of short- lived capital investment under § 168(k), and the § 163(j) net interest limitation. A particular emphasis is placed on state approaches to GILTI, which has often confounded lawmakers and revenue officials. 1 Jared Walczak, “Toward a State of Conformity: State Tax Codes a Year After Federal Tax Reform,” Tax Foundation, Jan. 28, 2019, https://taxfoundation.org/ state-conformity-one-year-after-tcja/. TAX FOUNDATION | 3 State Approaches to Federal Conformity All states incorporate parts of the federal tax code into their own system of taxation, but how they do so varies widely. In broad terms, however, approaches to IRC conformity can be divided into three classes: rolling, static, and selective.2 2 Harley T. Duncan, “Relationships Between Federal and State Income Taxes,” Federation of Tax Administrators, April 2005, 4-5, http://govinfo.library.unt. edu/taxreformpanel/meetings/pdf/incometax_04182005.pdf. FIGURE 1. States with rolling conformity automatically implement federal tax changes as they are enacted, unless the state specifically decouples from a provision. This autopilot approach tends to provide the greatest clarity and predictability for taxpayers, though at a modest cost of state control. Static (or “fixed date”) conformity also incorporates wholesale updates of the federal tax code as it existed at a specific point in time, rather than adopting all changes on a rolling basis. Some states with static conformity conform legislatively every year and are functionally identical to states with rolling conformity, albeit with a measure of added uncertainty. Others are inconsistent and may even conform to an outdated version of the IRC for many years.

As of January 1, 2020 TAX FOUNDATION | 4 Finally, a handful of states only conform selectively, incorporating certain federal provisions or definitions by reference, but omitting large swaths of the federal tax code and forgoing the use of federal definitions of income as their own starting points for calculation. No state, of course, conforms to every provision of the Internal Revenue Code. Each state offers its own set of modifications, additions, and subtractions to the code. Each adopts its own set of rules and definitions, frequently layered atop those flowing through from the federal code. But from definitions of income to exemptions to net operating losses, and even what filing statuses are available and whether a taxpayer can itemize their deductions, the federal tax code consistently informs state-level taxation. Twenty-one states and the District of Columbia use rolling conformity for both their individual and corporate income taxes, while two states—Massachusetts and Pennsylvania—employ rolling conformity exclusively for their corporate income taxes. Another 15 states use static conformity for both taxes, while the remaining states with income taxes use selective conformity, defining most major tax provisions independently of the federal tax code.

TAX FOUNDATION | 6 State Taxation of GILTI GILTI or not GILTI—in many states, the verdict is in doubt. Two years after enactment of the TCJA, many states would seem to conform to GILTI but have yet to issue any guidance to potential taxpayers, leaving them in the dark about any liability that may be accruing and giving rise to concerns of retroactivity should these states later determine that GILTI has been payable since tax year 2018. As a matter of sound policy, states should avoid taxing GILTI, which is far beyond the traditional scope of state taxation. Serious constitutional questions, and the prospect of costly litigation, give states an even stronger reason not to bring this international income provision into their tax base. If the intention is to avoid taxing GILTI, however, lawmakers should codify this commitment and clear up any uncertainty. The Global Intangible Low-Taxed Income inclusion is one of two guardrails in the TCJA, along with the Base Erosion Anti-Abuse Tax (BEAT), which can return some international income to the federal tax base. Although no state automatically conforms to the BEAT and states are unlikely to pursue such a provision on their own, the default position for many states is to incorporate GILTI, with profound consequences for the scope of their tax code. At the federal level, the GILTI inclusion functions in tandem with other provisions which tend to be lacking in state codes, like the credit for foreign taxes paid. Consequently, not only does conformity to GILTI involve state taxation of international income, but it also tends to yield a far more aggressive international tax regime than the one implemented by the federal government. Moreover, its purpose—to discourage profit shifting by parking intangible property in low-tax jurisdictions overseas3—is not served by inclusion in state tax codes. Although the name GILTI implies that the tax applies specifically to returns on intangible property (like patents and trademarks) parked in low-tax countries, that effect is only approximated by the interaction of multiple IRC provisions. Although GILTI calculations can be highly complex, in simplified form the tax falls on what are deemed the supernormal returns of foreign subsidiaries, less a deduction, less a calculated partial credit for foreign taxes paid. The inclusion (under IRC § 951A) is for what are considered “supernormal returns,” defined as income above 10 percent of qualified business asset investment less interest expenses. The rationale for this definition is that this is a reasonable rate of return on capital investment and that higher returns are likely to be royalty income or other income associated with profit shifting. (This is not, it bears noting, always the case.) A GILTI deduction is then offered at IRC § 250, currently worth 50 percent (declining to 37.5 percent after 2025), bringing the U.S. federal tax rate on this income from 21 to 10.5 percent (13.125 percent after 2025). Finally, business taxpayers may claim a credit equal to 80 percent of their foreign taxes paid on that income. These foreign tax credits are also subject to an overall limitation equal to U.S. tax liability times foreign profits divided by worldwide profits. In general, however, the higher the foreign tax liability, the lower the residual U.S. liability. 3 Kyle Pomerleau, “A Hybrid Approach: The Treatment of Foreign Profits Under the Tax Cuts and Jobs Act,” Tax Foundation, May 3, 2018, https:// taxfoundation.org/treatment-foreign-profits-tax-cuts-jobs-act/. TAX FOUNDATION | 7 FIGURE 2. 4 Joseph X. Donovan, Karl A. Frieden, Ferdinand S. Hogroian, and Chelsea A. Wood, “State Taxation of GILTI: Policy and Constitutional Ramifications,” State Tax Notes, Oct. 22, 2018, https://www.cost.org/globalassets/cost/state-tax-resources-pdf-pages/cost-studies-articles-reports/state-taxation-of-gilti- policy-and-constitutional-ramifications.pdf. Many states conform to the corporate code before credits or deductions, thus bringing in GILTI under § 951A, but without the 50 percent deduction or the credits for foreign taxes paid. Consequently, state taxation of GILTI is far more aggressive than federal taxation, and in particular, lacks any pretense of only applying to low-taxed foreign income. In some cases, state effective rates could rival the federal rate on GILTI.4 Any such taxation represents a substantial departure from states’ more typical water’s-edge tax systems, which generally avoid taxing international income, and raises serious constitutional questions. The issue is exacerbated by how some states include GILTI in their apportionment formulas. State apportionment regimes vary, but corporate income is always apportioned by states either on the basis of sales in the state as a percentage of total sales, or on some weighting of three factors: sales, payroll, and property. If, for instance, a U.S. company had $1 billion in domestic sales, and $100 million of that total was sold into a particular single sales factor state, then that state’s apportionment factor would be $100 million / $1 billion or 10 percent, meaning that 10 percent of the company’s taxable income would be apportioned to the state. Importantly, the $100 million in sales in that state appears both in the numerator (the full amount) and the denominator (along with sales elsewhere). Some states, however, are denying such factor representation for GILTI, including GILTI in the Source: State statutes and guidance; Tax Foundation research.

Such discrimination conflicts with Dormant Commerce Clause jurisprudence, which prohibits discrimination against interstate or foreign commerce. This also serves as a reminder that international income does not belong in state tax bases, as, in most instances, this anomalous treatment arises from tax codes founded on the assumption that state taxation stops at the water’s edge, which is to say that it does not extend to foreign income (or only in limited cases). When GILTI flows into a state tax system through inaction—by not proactively decoupling from the provision—nothing in the existing code is designed to take foreign factors of production into account. Some states have implemented or are exploring “factor relief,” a better alignment of factors in the numerator with the productive factors in the denominator, to address these concerns. Still, taxing GILTI—even with, but especially without, the 50 percent § 250 deduction and factor relief—is onerous, uncompetitive, and inconsistent with the purposes and traditional scope of state taxation. There is, moreover, an added wrinkle for states with separate (rather than combined) reporting, also on discriminatory taxation grounds. If a state does not include U.S.-based subsidiaries in a unitary group for taxation, it cannot include international subsidiaries (controlled foreign corporations) within the filing group for tax purposes. Congress has the sole authority to regulate commerce with foreign nations, and states may not treat international income less favorably than domestic income. States which use separate reporting and nevertheless seek to tax GILTI face a serious constitutional challenge, particularly under the precedent of Kraft v. Iowa Department of Revenue (1992), a U.S. Supreme Court case striking down a business tax that allowed a deduction for dividends received for domestic, but not foreign, subsidiaries.5 Importantly, although it resides in the same part of the federal tax code and is treated similarly for federal tax purposes, GILTI is not Subpart F income, and a state’s inclusion or exclusion of Subpart F income in its tax base has no bearing on its taxation of GILTI.6 A state’s treatment of the foreign dividends received deduction can, however, be relevant, as some states have eliminated GILTI liability by allowing it to be deducted as foreign dividend income. The following table indicates whether a state’s tax code, as written, applies to GILTI, along with whether the state has issued any guidance to that effect. We also show the percentage of apportionable GILTI taxed by the state after taking into account the foreign dividend income deduction and the Section 250 deduction, if applicable. It should be noted, however, that this calculation does not consider whether a state provides any factor relief, the absence of which can increase liability dramatically. Twenty-four states and the District of Columbia potentially tax GILTI, though only 17 states have issued guidance. In some states, the application of a § 250 deduction and an 80 percent dividends received deduction (DRD) eliminates all but 5 percent of GILTI, but 12 states have issued guidance imposing tax liability on a share of GILTI above the 5 percent threshold. 5 Kraft Gen.

Sources: State statutes and guidance; Tax Foundation research. TAX FOUNDATION | 10 States which tax GILTI, particularly absent factor representation, cannot expect to escape a legal battle. The Supreme Court has made clear that “[t]he factor or factors used in the apportionment formula must actually reflect a reasonable sense of how income is generated,”7 a requirement transparently violated if the denominator either omits or only includes a portion of the factors that generated the GILTI included in the numerator. And while states possess limited authority to have distinct approaches for interstate (or international) commerce if intended to compensate for a provision that only burdens intrastate commerce, they operate with a short leash: “To justify a charge on interstate commerce as a compensatory tax, a State must, as a threshold matter, ‘identif[y] the [intrastate tax] burden for which the State is attempting to compensate.’ Once that burden has been identified, the tax on interstate commerce must be shown roughly to approximate—but not exceed—the amount of the tax on intrastate commerce.”8 There is nothing compensatory about taxing GILTI without factor representation.9 Finally, even if states tailor their GILTI regimes narrowly enough to survive any legal challenge, its inclusion dramatically decreases the state’s tax competitiveness by markedly increasing the state tax burden on multinational companies with headquarters in the state. Discriminating against multinational companies which choose to headquarter in one’s state is not only bad tax policy but also clearly counterproductive, rendering the state’s corporate income tax a far greater liability and encouraging corporate relocation. Foreign-Derived Intangible Income Whereas GILTI involves the taxation of the foreign intangible income of domestic corporations, the foreign-derived intangible income (FDII) deduction provides a benefit to companies that generate export-related income on U.S.-based intangible property. Many have termed this the carrot-and-stick approach to international taxation, where FDII is the carrot and GILTI the stick.10 Like the deduction against GILTI, the FDII deduction is located in IRC § 250, though the two are separate and should not be confused. States which conform to the GILTI deduction in that IRC section typically offer the FDII deduction as well, but a few have legislated the matter separately. Just as there is little justification for taxing GILTI at the state level, there is scant rationale for providing a FDII deduction, though denying FDII while taxing GILTI represents a particularly aggressive approach. Twenty-four states provide an FDII deduction. Three states which deny the FDII deduction tax a nominal amount of GILTI (Connecticut, Massachusetts, and New York), while four others tax GILTI more broadly despite decoupling from the FDII deduction (Maryland, New Hampshire, Oregon, and Rhode Island). To date, Utah has not issued guidance on the taxation of GILTI, but its tax code would appear to tax it, while not bringing in the FDII deduction. 7 Container Corp. v.

Repatriation Income Prior to enactment of federal tax reform, American corporations had about $2.6 trillion in overseas reinvested earnings.11 Under the old “worldwide” system of taxation, U.S. corporations paid the difference between the U.S. statutory corporate income tax rate of 35 percent and the statutory rate in the other nation where the income was earned. However, that liability was deferred so long as the income was reinvested. As part of the transition to a territorial tax code, these deferred earnings were “deemed” to have been repatriated, meaning they are immediately taxable by the federal government at rates of 15.5 percent on liquid assets and 8.0 percent on illiquid assets. This repatriated income is included in what is known as Subpart F income. 11 Erica York, “Evaluating the Changed Incentives for Repatriating Foreign Earnings,” Tax Foundation, Sept. 27, 2018, https://taxfoundation.org/ tax-cuts-and-jobs-act-repatriation/. TAX FOUNDATION | 12 FIGURE 3. 12 Connecticut Public Act No. 18-49 (2018). Whether states include Subpart F income in their tax base and whether they conform to the new deduction for foreign dividends received helps dictate whether they receive additional revenue from income “deemed” repatriated. Deemed repatriation is a one-time event, based on income held overseas at the end of 2017, though its impact continues since states continue to assert a tax claim based on that event. Companies have the option to spread payments over eight years for federal tax purposes, but only two states—Oregon and Utah—conform to this installment payment option. When a foreign subsidiary of a domestic corporation pays a dividend to its U.S. parent, the federal government provides a deduction for the foreign-source portion of dividends received, consistent with the principles of a territorial tax system. States can theoretically diverge from federal treatment in two ways: in their definitions of dividends received (Rhode Island, for instance, does not consider repatriation income a foreign dividend) and whether they provide the 100 percent deduction of foreign dividends. Anomalously, repatriation income is fully deductible under Connecticut’s dividends received deduction, but subject to a 5 percent addback under a 2018 law.12 Taxes Repatriation Income Does Not Tax Repatriation Income TAX FOUNDATION State Taxation of Repatriation Income Note: (a) Colorado provides an exclusion based on the federal credit for foreign taxes paid.

TAX FOUNDATION | 14 Capital Investment and Manufacturing Activity The TCJA also allows the full expensing of short-lived capital assets—essentially, investment in machinery and equipment—through 2022, after which the provision phases out. The corporate income tax is imposed on net income (after expenses), but traditionally, investment costs must be amortized over many years, following asset depreciation schedules. This creates a bias against investment, and this disparate treatment has long been in the crosshairs of reformers. The new law does not eliminate depreciation schedules altogether but allows purchases of machinery and equipment to be expensed immediately. This new cost recovery system builds on the prior “bonus depreciation” regime, under which 50 percent of the cost of new machinery and equipment could be expensed in the first year. The new federal law’s more favorable treatment of capital investment flows through to some states. Federal law now allows purchases of short-lived capital assets (machinery and equipment) to be expensed immediately, rather than depreciated over many years. This replaces the prior bonus depreciation regime, which offered accelerated (but not immediate) depreciation. Sixteen states conform to IRC § 168(k) and thus follow the federal government in offering full expensing of machinery and equipment purchases. Another three states (Florida, Minnesota, and North Carolina) conform with partial addbacks, allowing a given percentage (for instance, 20 percent in Minnesota) of the bonus depreciation offered at the federal level. Although full expensing reduces state revenue, it is also highly pro-growth because it reduces the tax code’s otherwise punitive treatment of investment compared to other business expenses,13 and states that have yet to incorporate cost recovery in their codes would do well to conform to this provision. Accepting this cost should be made easier in that most states enjoy a broader overall tax base due to federal tax reform. Within this context, it makes sense to incorporate provisions which drive economic expansion. Indeed, states should consider making their own expensing regimes permanent, retaining this competitive provision even if the federal policy is allowed to expire. At the same time, federal law now restricts the deduction of business interest, limiting the deduction to 30 percent of modified income, with the ability to carry the remainder to future tax years. For the first four years, the definition of modified income is earnings before interest, taxes, depreciation, and amortization (EBITDA); afterwards, a more restrictive standard of gross income less depreciation or amortization (EBIT) goes into effect.14 13 Erica York, “Cost Recovery Treatment Short of Full Expensing Creates a Drag on Economic Growth,” Tax Foundation, Sept. 17, 2018, https://taxfoundation. org/cost-recovery-treatment-short-full-expensing-creates-drag-economic-growth/; and Kyle Pomerleau, “Why Full Expensing Encourages More Investment than a Corporate Rate Cut,” Tax Foundation, May 3, 2017, https://taxfoundation.org/full-expensing-corporate-rate-investment/. 14 Stephen J.

These changes mean that a greater share of interest costs will be taxable, increasing revenue. Of particular note, additional capital investment can limit interest deductibility under EBIT. Given this change, which increases the cost of investment, states would do well to ensure that they also conform to the new full expensing provision, which was intended as a counterbalance.

Many base-broadening provisions, discussed in our prior conformity updates, were relatively straightforward. Some states saw this federal-driven broadening of state tax bases as an opportunity to cut rates or make other changes; others reversed many or all the base adjustments; and still others quietly embraced the additional revenue.15 All too often, states were happy to accept the additional revenue, but made no effort to incorporate offsetting provisions like full expensing of capital investment. Conforming to the expensing provision would improve states’ tax structure and, more importantly, enhance their business competitiveness. But it is with the international provisions of the TCJA, and particularly with GILTI and deemed repatriation, where confusion still reigns. More than two years after enactment of the new federal tax law, seven states and the District of Columbia have yet to issue guidance on GILTI even though their tax codes appear to incorporate it, and 17 states have issued guidance or enacted legislation incorporating some amount of GILTI in their base, often without factor representation. States should avoid the temptation to see international income as an untapped source of revenue, taking steps to provide certainty and avoid punitive corporate taxation. States have delayed long enough; there is no time like the present to ensure that state tax codes are oriented toward economic growth. 15 Jared Walczak, “Tax Trends Heading Into 2019,” Tax Foundation, Dec. 19, 2018, https://taxfoundation.org/state-tax-trends-2019/.
